Description/Abstract

Adaptation of the tap profile in subband adaptive system identification problems can further enance the efficient use of commputational resources if implemented on a DSP with an otherwise too tight benchmark performance. Here, we derive a generalisation of previous work to extend tap-assignment algorithms to a new class of oversampled filter banks with non-uniform bandwidths and different subsampling rations. We compare efficiency and adaptation results for this approach to the critically sampled case and a fullband identification with same complexity.
